I was one hour into the Le Mans endurance showcase event, and messed up so I decided to rewind the race. Upon doing so, both headlights of the Audi R18 I was in shut off. Neither of them had been damaged before rewinding, as I had just completed a pit stop at the beginning of the lap. Because of the lights going out, and me being too far into the lap to rewind back to the pits, I crashed on the straight away and severely damaged my car because I couldn't see. I had no choice but to exit the race because there was no way I would be able to complete the lap and maintain my postion whatsoever. Has anyone else had this issue? I'm very frustrated right now, because I lost what would've been 180000 driver xp (boost mod) plus around 1 mil+ credits (30% dare mod, difficulty, assists, level up rewards, and affinity).

Doesn't exactly match your described circumstance, but I suspect this is related - from VoodooUomo's stickied patch notes:

* Headlight repair in the pits
If you’ve been doing night enduros with sim damage and no rewind, you probably wanted this to work and now it does! Just one note: there is a separate issue where the headlights may go back to a broken state if rewind is used after they’re repaired in the pits. We’re tracking this issue separately. Hopefully the headlight repair in the pits still proves valuable to you, I know quite a few of you turn off rewind for the extra rewards or authenticity (I do!).

Newbie to the forums here, but I was so frustrated after spending over an hour without touching the rewind on the Le Mans Endurance race, sat nice in 1st, just had a pit stop and half race distance, 30 seconds up and my wife walks straight past the TV. I veer off track but don't crash but use the rewind button to sort it out. Now my headlights don't work?! No crash, just used the rewind feature and boom, gone! I had mods on too for boosting xp etc. I don't often get time to play on my Xbox and this unfortunate event has made me very grumpy indeed! Help please?

Same problem here.
On lap 12 out of 30 on Le mans endurance, driving the #2 Audi R15++.
Forced to abandon mission.

Side note: Had 3x 100% Exp booster active, and I really hope they can be reclaimed.
